I skimmed the abstract when punnyguy linked it in the other thread, and added some very general thoughts, but I haven’t read all 17 pages of the study.
I think @ActivitiesGuy (if he’s not too swamped with work) would be better suited to giving thoughts on the statistics and general approach. It’s not really my area of expertise. I’ll read it and see if I can say anything useful.
I think he’s very smart lol. That sounds about exactly like what I would have guessed on a first impression.
